Specification of Letters Patent.

Patented Sept. as, 1915.

Application filed February 10, 1915. Serial No. 7,392.

To all whom 2'25 mayconcern 1 Be it known that we, JOHN W. LINVILLE and CARL C. TILLMAN, citizens of the United States, residing at Toledo, in thecounty of Lucas, State of Ohio, have invented a new and useful Goring-Machine, of which the following is a specification.

This invention relates to coring machines and is especially designed for'usein'coring tomatoes prior to being canned.

One of the objects of the invention is to provide improved means for holding the tomatoes during the coring operation, there being means operating in properly timed relation with the coring means for removing the blossom from the tomato.

A further object is to provide means for feeding the tomatoes or the like to the coring mechanism, said feeding means operating intermittently so that the coring is effected during each pause in the movement of the feeding mechanism.

With the foregoing and other objects in view which willappear as the description proceeds, the invention residesin the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings, Figure l is a side eleva-- tion of a machine embodying the present improvements Fig. 2 is a plan View thereof. Fig. 3 is an end elevation of the machine, the carrier belt being removed. Fig. 1 is a detail view of one of the coring knives. Fig. 5 is an enlarged side elevation of one of the blossom removing knives and its-trip rod. Fig. 6 is a face view of said blossom removing knife. Fig. 7 is a detail view of one of.

the holding plates. 7

Referring to the figures by characters of reference 1 designates a suitable frame provided atone end with a transverse shaft 2 while another transverse shaft 3 is journaled in the other end portion thereof. Shaft 3 is provided with a ratchet wheel 4: and this ratchet wheelis normally engaged by a dog 5 at the upper end of a rod 6, this dog being normally heldin engagement with the ratchet wheel by meansbf a spring 7. Rod 6 is pivotally connectedto a wheel 8 which receives motion through a belt or chain 9 from V a pulley or sprocket 10 secured to a drive shaft 11 'journaled within the bottom portion of the frame 1. This shaft 11 has the usual fixed and loose pulleys 12 and 13. for engagement by a drive belt.

Secured to the shafts 2 and 3 are wheels 14 arranged in pairs, these wheels being either in the form of pulleys or sprockets, as desired. The said wheels engage endless belts orchains 15 which also engage and are driven by pulleys or sprocket wheels 16 rotating with the shaft 3. The belts or chains of each pair are connected at regular inter vals by holding plates 17 one of which has been shown in detail in Fig. 7. Each holding plate is provided with a central enlargement 18 in which an opening, preferably circular, is provided as shown at 19, this opening being provided at diametrically opposed points with slots or extensions 20 disposed along lines parallel with the path of movement of the belts or chains. The

said holding plates are so spaced that dur- Guides 25 extend downwardly from the top portion 24: and constitute parts of the frame 1. These guides are slidably engaged by a cross head 26 in which suitable openings 27 are provided through which the guides 25 extend. This cross head extends transversely above the conveyors 15 and journaled upon the cross head is a train of gears made up of large gears 28 and small intermediate gears 29. One gear 28 is provided above each pair of conveyer belts 15 and one of these gears 28 receives motion, through a gear 30, from a gear 31 which is feathered on the shaft 23. As itwill be seen that during the rotation of shaft 23 the cross head 26 can be raised or lowered along its guides without interfering with the transmission of motion from said shaft 23 to the gears on the cross head.

Secured to the shaft 11 are gears 32 each of which meshes with a larger gear 33.

These large gears'33 are'connected by pit= men 34 to the end portions of the cross head '26 so that during the rotation of shaft 7 11 the said cross head will'be raised and lowered.

Depending from and revoluble with each gear 28 is a stem 35 provided with a coring blade 36, the blades all being revoluble about vertical axes. Each blade is surrounded by a spiral spring 37 preferably formed of light wire so that, when the cross head is lowered, the several springs will engage and press lightly upon the tomatoes or other articles to be acted upon during the insertion of the blades 36 into said articles and during therotationof the blades.

Located directly under or in vertical alinement with each of the blades 36 and close to and under the paths of the holding;

plates 17, is a transverse shaft 3S having a radial arm 39 extending therefrom and into the path of a tappet rod 40 extending from the cross head 26. Secured to and extending from the shaft38 are arms 41 each of which is provided at its free end with a blade or scoop 42 adapted to work in a vertical plane passing underneath the blade 36 thereabove. It is to be understood of course that one of the blades 42 is pro- 1 vided for each: blade 36 and that the blades 42 are normally positioned below the paths of the uppermost holding plates 17.

It is to be understood that when shaft 11 V is in operation motion will be transmitted therefrom through the gears 32 and 33 so as to reciprocate the crosshead 26 upon the guides 25. Shaft 23 is'constantlyv rotating so that, as the cross head moves downwardly and upwardly, the coring 1 blades 36 are rotating rapidly. Further more, during the completion of each downwardmovement of the cross head 26, the tappet1rod'40 comesagainst, the arm 39 and thus causes the arms 41 to swing up-- wardly so that the scoop-like blades 42 thereon will plow into the bottom portionsof the articles supported thereabove, thereby removing the blossoms from the articles, should they be tomatoes. Any suitable means may be provided for automatically returning the arms 41 to their normal positiqns when released. For example a spring 7 43 may be attached to the arm 39 as shown in Figs. land 3. I i The ratchet wheel 4 and its operating mechanism are so proportioned that during ing plates and while the articles ar'e thus held yieldingly, the blades 36 will enter and rotate within the articles'soas to remove the cores. During this operation the blades 42 will be operated as hereinbefore described to remove the blossoms from the articles, Upon the completion of the cor;

ing operation, the articles will be conveyed to delivery spouts 44 which will direct the articles, for example, to a peeling machine such as constitutes the subject matter of a separate application filed by us; 'The notchesv or recesses 20 are provided in the, holding plate to permit the blades 42 towork through the plates readily. V What is claimed is 3 g 1. A coring machine including means for feeding an article with a step by step movement, means for coring the article during.

apause in its movement, and means for antomatically cutting out a portion of the bottom of the article while being cored.
